SOFA BED.

SPECIFICATION forming part of Letters Patent No. 395,247, dated December 25, 1888.

Application filed April 25, 1888. Serial No. 271,835. (No model.)

the seat as a bed, means being provided to secure it in either position, all as well known.

This invention consists of a support of the back in a horizontal position, composed of a leg (preferably one at each of its ends) which atone end is suspended by a pin from and to turn in and travel along a slotted way of and running at right angles to the length of the back, in. combination with two parallel links or bars, each jointed at one end to opposite points in the length of the leg and at their other end to the seat-frame or a stationary part thereof, and all in a manner to secure in the lowering of the back a swing of the leg into position at right angles to the back, and

thus a position of a support thereto, and in the lifting of the back a swing of the leg toward and, as it were, to fold it against the back; and, in combination with the above, the invention also consists of a support for the back in its vertical position, composed of a sliding bolt fixed to the back and arranged for an engagement with said slotted way and engaged to act as a stop to the travel of the connection of said leg-support for the back along said way; and, again, the invention consists of a spring applied to the link-connection of the leg with the back to assist in raising the back from a horizontal to a vertical position.

In the drawings forming part of this specification, Figure 1 is a back elevation of the sofa-frame, not upholstered. Fig. 2 is a transverse vertical section, line 2 2, Fig.1.

Fig. 3 is a sect-ion similar to Fig. 2,with the back in a horizontal position; Figs. 4, 5, and 6, detail views.

In the drawings, A represents the seat frame of a sofa, B B the arm-frames at opposite ends of the seat-frame, and C the backframe, all, except as to the features of thisinvention, as ordinary and well. known.

The back-frame U, at one end along its under edge, (1 is hinged to the rear edge, A of the seat-frame A, and at each end it has a section or wing, 0 made separate from and hinged to it to make with the back in its vertical position continuations thereof. at and across the rear of the arm-frames i313, and with the back in its horizontal position to serve as contimiations of the arm-frames across the width of the back-frame, having lirst been suitably raised and su ported therefor, as will. hereinafter appear.

I) D are legs, one at the opposite ends of the central portion of the back and for the support of the back when it has been lowered to a horizontal posit-ion to serve with the seat as a bed. lhe legs are joined by a rail, D Each leg l), at one end, has a pin, ('1, which enters a slotted way,l1, extemling at right angles to the length of the back, and each leg, at opposite points in its length, has one end of parallel links or bars E E pivoted or hinged, as at (I, to it, and these links, at their opposite ends, are pivoted or hinged, .as at f, to the scat-frame or other suitable stationary part of the sofa.

ln raising the back to a vertical or lowering it to a horizontal position, each leg I), by its pin (1, travels along and turns in the slotted way Z) of the back, and the links or bars E E swing by their pivots or hinges at (7 j" on the leg and seat-frznne, and thus in the lifting of the back-frame the legs are moved to a position of fold, as it were, against the back, and in the lowering of the back-frame the legs are moved to a position to serve as leg-supports to the back-frame.

ll ll are spring slidebolts, of any ordinary or other suitable construction, located at the opposite ends of the central portion of the back-frame, and each in position to be engaged with the slotted way I) of the backframe at the correspoinling end and just above the pin a of the leg-support, engaging said way when the back is in its vertical position. The bolts l-I, engaged as stated, restrain and hold the legs against travel along the slotted way with which each is engaged, as described, and thus the back is made secure in its vertical position. The release of the slide-bolts, as is obvious, sets the back free to be lowered to a horizontal position, and, preferably, the bolts are connected by a common cord, K, passing through guide-eyes L of the backframe, so as to be released by simply pulling on said cord, as well known in other sofa, lounge and similar beds.

Each hinged end wing, C of the backframe 0 contains a fixed block projection, M, having a more or less rounded or camshaped edge, M .to run and bear upon the upper edge, N of a stationary block, N, which is-secured to the seat-frame, and its said edge is at a height such as to secure, from the running thereon of the projecting block of the end wing of the back as the back is lowered to ,a horizontal position, the lifting of the end wing into a position of continuation of the sofa-arm at the corresponding end of the sofa.

G is a wire spring with a bend, I, having legs, each continued in a coil, Q, at right ngles to its length, and having a free end, B. Each link-bar E of the leg-connection with the seat-frame has a spring, 0, arranged to press by its bend against it. The coils Q of each spring 0 surround and are confined on a separate cross-bar, S, of and between earpieces T, which are secured to the seat-frame or other suitable stationary part, and the free end B of each spring, for the efit'ective action of the spring, as well known, is confined against a rest, U, of the ear-pieces. The springs O assist in the raising of the back, and are used more particularly for that purpose, although, as is obvious, they act also as .braces to the hinge-connection of the links or bars E upon which they press with the seat-frame.

Theconnectionpin a of each leg D has a peripheral flange, g, Fig. 4, to allow the pin to engage and interlock with the edges of the slotted way 1'), in which it travels, and thereby prevent accidental disengagement of the pin from the way. Again, each end of the slotted way I) has a depression, It, (only one end shown, Fig. 2,) for the seating therein of the connection-pin a between it and the legs D. Theengaging end of each sliding bolt H is beveled off on one side, similar to a latch-bolt, to allow the connection-pin a of the leg D, as it travels along its slotted way I) in raising the back-frame, to freely force the sliding bolt back and out of its path.

All parts of the frames herein described, as well known, are to be upholstered.

Having thus described my invention, What I claim, and desire to secure byLetters Patent, 1s-

1. In a sofa, lounge, (to, having the backframe hinged to the seat-frame, a support for the back-frame in a horizontal position, com posed of a leg, D, a guideway, a, of and across the length of the back-frame, and having said leg connected to it to turn in. and travel along it, and links or bars E E pivoted or hinged at their opposite ends to opposite points in the length of said leg and to a stationary support, substantially as described, for the purpose specified.

2. In a sofa, lounge, 850., having the backframe hinged to the seat-frame, a support for the back-frame in a horizontal position, composed of a leg, D, a guideway, a, .of and across the length of the back-frame, and .having said leg connected to it to turn in and travel along it, and links or bars E E pivoted or hinged at their opposite ends to opposite points in the length of said leg and to a stationary support, in combination with .a bolt, H, of the back-frame, to engage said guideway above the connection of leg therewith when the back-frame is vertical, substantially as described, for the purpose specified.

In a sofa, lounge, 850., having the backframe hinged to the seat-frame, a support for the back-frame in a horizontal position, composed of a leg, D, a guideway, a, of and across the length of the back-frame, and having said leg connected to it to turn in and travel along it, and links or bars E E pivoted or hinged at their opposite ends to opposite points in the length of said leg and to a stationarysupport, and a spring, 0, arranged to press on the link-bar E substantially as described, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
